saving the imported 3ds object as .blender file first before doing a 
povray render from with-in blender ... more of a curiosity on my part 
than anything else because of the problem that i'm seeing!

it /seems/ to be with how the object was built. now i'm speaking in pov. 
-z behind, -x left +x right.

example: my current project 8 melted candles on a box, wax dripping down 
over the edge.  the candles are roughly in two rows and the x position 
is flipped: instead of 1-2-3-4 i get 2-1-4-3. i took each of the candles 
(and wicks) cleared rotation, location, scale and origin, then properly 
built the object centered at 0,0,0 the placed them in the scene. setting 
of the origin seems key. now i'm able to select the wick of each candle 
then snap 3d cursor to the wick for /proper/ location information, 
because in povray i'm going to place a media/light source flame on each 
candle.

the render options tab (little camera)

i don't do that ... usually just add simple texture to identify in 
scene. i do material work either in pose or pov ... ray
